Those Floscans are nice if they work. My buddy has one that hasn't worked in a few years, we have to try to fix it. I think they cost anywhere from 5 or $600. Kind of a high end investment but if it saved you 10 gallons on an offshore trip this year that would be $40, so probably worth it.

A friend of mine told me that you can pretty much do the same thing with your tachometer. I'm sure going to try this year. Although, my 150hp dosen't really use that much fuel. But, then again, any help will be gladdly accepted.

I've got one and I love it. Only took me about 16 hours to install though.....lol.

The second time around will no doubt be easier.

Actually you really only need to use a flow scan once. Once you determine the GPH and MPG over the RPM range, it is pretty much fixed for the life of the boat. Yes it will change slightly with load but not much.

That said, I like them and my next boat will have one.
